XLGAMES' Civilization Online is 60% completed, Jake Song said in a recent interview.
Song said that the multiplayer online version of the classic Civilization series is more than halfway done in preparation for its open beta. He also announced that testing should commence in the first half of this year.
One interesting tidbit that came out of the interview was a classification of Civilization Online as a more casual spin on the series that won't require as much time invested as the single-player variants.
